What's the chance of getting at least a single 1 on a 64 sided die thrown 64 times?
I believe we can calculate that by multiplying the chances of not rolling a 1 in each of the 64 throws, which would be $(\frac{63}{64})^{64}$, then $(1 - 0.36)$ or so gives us approximately a 63% chance of rolling at least a single 1, but logically speaking, shouldn't we anticipate seeing each number roughly once on average if the die is fair?
